Run/test a generic Linux based container

To run/test a linux based container:


Ensure docker is running.
  systemctl status docker

Then pull  the image:
  sudo  docker pull quay.io/<repo name>/<image name> 

Get the image id:

sudo docker  images | grep <image name>

Then run the image:

  docker run  -it  f4f4224a731c   /usr/bin/bash

Here f4f4224a731c is an example image id.


There is a assumption made here that bash is installed in the linux image.
